Center for Isotope Geochemistry

The Center for Isotope Geochemistry (CIG) is a joint-institution research center, with labs both at LBNL and UC Berkeley. This state-of-the-art analytical facility was established in 1988 to measure the concentrations and isotopic compositions of elements in rocks, minerals, and fluids in the earth’s crust, atmosphere, and oceans. CIG has a community of roughly 25 people—scientists, research lab staff, postdoctoral researchers, graduate students, and administrative/computer support staff. It is directed by Donald J. DePaolo, (Associate Lab Director for Energy Sciences) at Lawrence Berkeley National Lab, and Class of 1951 Professor of Geochemistry, Department of Earth and Planetary Science, UC Berkeley.

Three scientists affiliated with EESA have been elected as members of the National Academy of Sciences. Kristie Boering is a faculty scientist in the Climate & Ecosystem Sciences Division at Berkeley Lab and a UC Berkeley professor of chemistry and earth and planetary science who studies physical, environmental, and atmospheric chemistry; climate change; and earth and…

EESA Scientists were able to use the new synchrotron Infrared Nano Spectroscopy (SINS) capability at Advanced Light Source. Above: Diagrams of the setup of (a) the Germanium-hemisphere enhanced attenuated total reflection (Ge micro-ATR) and (b) the resonance enhanced SINS. Berkeley Lab scientists have identified a way to use machine learning to connect fine-…

Two papers published in 2017 by geophysics researchers within the Energy Geosciences Division have been honored by the Society of Exploration Geophysicists. Geophysics Department Head Jonathan Ajo-Franklin was notified that the studies received Honorable Mention in the category of Best Paper in Geophysics in April. The papers published by the society are: An effective-medium model for P-wave…

A new Earth System Model (ESM) unveiled today will have weather scale resolution and use advanced computers to simulate aspects of Earth’s variability and decadal changes expected to impact the U.S. energy sector in coming years. After four years of development, the Energy Exascale Earth System Model (E3SM) will be released to the broader scientific…

On April 10, Berkeley Lab and France’s Geological Survey, BRGM (Bureau de Recherches Géologiques et Minières), signed a Memorandum of Understanding representing their intent to expand a collaborative partnership. The French geological survey is one of Berkeley Lab’s key European counterparts in working to address the need to protect and sustain Earth’s energy and environmental…
